STRAW-STACKER.

\ SPECIFICATION forming part of Letters Patent No. 289,204, dated November 27, 1888,

' Application filed Aprjil14,1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, Asa H. ALLISON, of Knightstown, in the county of Henry and State of Indiana, have invented certain new and useful Improvements in Straw-Stackers; and I dohereby declare that the following is a full, clear, and exact description thereof,

reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form specification, in which Figure 1 is a section taken vertically and longitudinally through the center of my improved stacker, showing the vibrating carrierplatform elevated in a position for operation. Fig. 2 is a transverse section through Fig. 1, taken in the vertical plane indicated by dotted line ac thereon. Fig. 3 is an elevation of the left-hand side of my machine when it is folded for transportation. Fig. 4 is a top view of part of this the shape of the guide or chute. This invention relates to machines for conducting straw from a thrashing-machine and stacking the same; and it consists in certain novel improvements 011 the machine for which Letters Patent numbered 27 7 ,400 were granted to me, bearing date May 8, 1883, which will be fully understood from the following description, when taken in connection with the annexed drawings.

A A designate the sills of my stacker,which are connected together by cross-bars, so asto constitute a substantialfoundation for. the

working parts. Near one end of this founda- .tion inclined standards B B are erected and rigidly secured to the sills A A, and to the upper ends of these standards, and also to said sills, inclined guides and braces 13 B are sew cured.

O designates a sash, consisting of horizontal cross-pieces connected together by pieces at right angles to them. The ends of the cross-pieces of the sash are fitted between the ratchet and paw]. XVhen allowed to do so, the sash will descend by its own weight and that of the parts which it supports. i

E designates a vibrating carrier-platform, which may be made of folding sections jointed at a, so that it can be folded, as shown in Fig. 3, when the machine is not in use. This platform has a bottom and sides, an endless carrier, 1E running on pulleys H H, and also a backwardly-flaring chute or straw-guide, F, which latter I prefer to make of thick sheet metal stiffened by a brace, b. lVhen seen from above, the shape of the chute or guide is semicircular, with forwardly-extended wings, and the vertical center of the semicircle coincides with the axis of a swivel rod or post, G, which is the axis of the horizontal vibration of the entire carrier-platform. This chute F will guide and direct all of the straw leaving a thrasher upon the rear end of the carrierplatform, no matter at what angle this platform may be adjusted with respect to the straw-discharge of the thrashing-machine.

The swivel rod or post G above referred to is supported by a bracketstep, c, secured to the lower crossbar of the sash O, and guided by a bracket, a, secured to the upper bar of the sash. The upper end of the swivel rod or post Ghas a U-shaped cross-head, G", rigidly securedtoit, to the arms of which cross-head the carrier-platform E is pivoted by the horizontal shaft H of the rear carrier-pulleys, H. It will be seen that the platform E can bevi brated both horizontally and vertically, and that it canbe bodily raised and lowered by means of its sash while in motion.

The endless carrier, by which the straw is elevated and dischargedv upon a stack, receives its movement in the following manner, no matter what may be the position of the carrierplatform: I designates a belt-drum, which is fast on a shaft I havin its bearin s in boxes on sash C, and provided with a hand-crank or power-pulley, I", on one end. Around this drum passes a belt, d, which is carried up and traveling off the drum J, I employ a concave idler or auxiliary pulley, K, which has its end hearings in a yoke, L, arranged in a plane below the drum J and applied on the swivelpost G.

I will now describe my devices for adjusting the carrier-platform at different angles vertically. My object is to keep the discharge end of the carrier-platform as near the top of the stack as possible while building it, to prevent the wind from scattering the falling straw, and at the same time to provide efiicient means for raising the stacker bodily as the height of the stack increases. M designates a horizontal semicircular support or track, which is rigidly secured to the bottom of the sash O by means of pendants j and back braces, I, or by any other suitable means.

N designates an arm, which is pivoted to an offset, on, secured fast to the bottom of the sash G, at the middle of the width thereof. The vertical axis of the pivot of this arm preferably coincides with the of the swivel-post G. This arm is supported upon the track M by an anti-friction roller, 12. and the free end of the arm has detachably pivoted to it, at n, a supporting-bar, P, the limbs of the broad U- shaped cross-head I of which receive freely through their ends the rods B. These rods R are secured by their angular upturned ends to strips T, which are rigidly secured to the sides of the carrier-platform E.

S designates a Windlass, on one end of which is a hand-crank, s, and a ratchet and pawl. To the Windlass S is secured one end of a rope or chain, t, the other end of which is secured to the arm N at the point shown in Figs. 1 and 3. It will be seen that the outer support (or supports) for the carrier-platform is free to vibrate to the right or left with the rear supports; also, that by means of the Windlass S the upper ends of the crosshead and its bar P can be vibrated about the joint at a, and the discharge end of said carrier-platform elevated or depressed for the purpose above described.

The machine I have above described is reduced in size for storage or convenient transportion by depressing the sash G to its fullest extent, folding the outer section of the carrier-platform upon the inner section, remov ing the pin from the joint at n, and passing the end of the supporting-bar I through the sash. The prop A, which is pivoted to the sills A, is then erected, and the free ends of the carrier-platform are supported upon the transverse bar A of said prop. The relative positions of the several parts now present the appearance represented by Fig. 3.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

the purposes described.

2. The combination, in a straw-stacker having a carrier-platform which will vibrate vertically and horizontally, and which is movable up and down bodily, of a horizontal circular track, a supporting-arm movable on this track, a support hinged to said arm, guiderods fixed to the carrier-platform, having the upper ends of said support loosely attached to them, and a Windlass and rope for raising the discharge end of the said carrier-platform, all constructed and adapted to operate substantially in the manner and for the purposes de scribed.

3. In a straw-stacker, the combination of a sash for supporting the carrier-platform, a track secured to this sash for supporting the discharge end of the platform, a hinged supporting bar connected to the platform, and means for adjusting said bar about its hinge, all constructed and adapted to operate substantially in the manner and for the purposes described.

4. In a straw-carrier, the carrier-platform, a movable supporting-sash therefor movable on inclined beams, the swivel-post and its cross-head mounted in said sash, the drivingbelt drum borne bysaid sash, the driven drum borne by the arms of the cross-head of said post, the transmitting-pulley e on the shaft of the driven drum, and the pulley on the shaft of the rear end pulleys of the straw-carrier,all constructed and adapted to operate substantially in the manner and for the purposes de scribed.

5. The combination of a sectional folding platform which is capable of vertical vibration, a supporting-sash therefor which can be moved up and down while in operation, a folding forward support, a folding prop, a base-frame, and an upright frame, all constructed and adapted to operate substantially in the manner and for the purposes described.

In-testimony that I claim the foregoing as my own I aiiix my signature in presence of two witnesses.

ASA H. ALLISON.
